Hi,
I think that AC cap location is does not matter. You should be more
aware that capacitance body might change the characteristic impedance of
your transmission line. In this case you should adjust transmission line
width.
Actually is best described by Dr. Howard Johnson's "Potholes" analogy.=20

Hi all,
In case of AC coupled signals does anyone know of an optimum placement
for the caps? I mean should they be placed near the source, receiver,
middle of the transmission line?
How much difference does it make in the opening of the eye?
The signals are differential CML running at 3.0Gbps
Thanks,
Nikhil=20
